PRINTING DEVICE AND TYPE HOLDER THEREFOR.

Application filed January 13, 1923. Serial 1W0. 612,464.

To all whom it may concern:

Be it known that I, Morons J. HOFFMAN,- a citizen of the United States, and a resident of Chicago, Cook County, and State of Illinois, have invented certain new and useful Improvements in Printing Devices and Type Holders Therefor, of which the following is declared to be a full, clear, and exact description.

This invention relates to printing devices and type holders therefor, and its principal object is to provide a simple, practical and efiicient device for printing names, dates, or other information upon cards, slips, sheets or the like. In its present form it has been designed for printing names and dates upon workmens time cards, but ohviously it is not limited to such use, as it may be used for printing any desired information upon any kind of cards, strips or sheets. Another object is to provide a printing device which may print on both sides of cards orthe like at one and the same time. Another object is to provide a printing device containing a. number of lines of set type, arranged circumferentially about a type carrier, and automatic means for bringing the succeeding lines into printing position,.one after the other. In this connection the lines of type may be set to print names, whereby many workmens time cards may be printed with their respective names on one or both sides of the time cards. Another object is to provide simple means asso-, ciated with the name-printing-type, for printing dates, on the same line as the name is printed. Another object is to provide simple and convenient means whereby a line of type may be set up to form a name or names, words, or other information, and whereby the line of type maybe locked up so that it may be readily handled. The invention includes a type carrier in which the locked lines of type may be removably secured, whereby impressions may be made from the type-whenever required, The invention consists in the several novel features hereinafter fully set forth and claimed.

The invention is clearly illustrated in'the accompanying drawing, in which:

Fig. 1 is a vertical, cross section taken through a printing device embodying the preferred form of the invention; Fig. 2 1s a vertical, longitudinal section thereof takenon the line 22 of Fig. 1; Fig. 3 is a plan with certain portions broken away; Fig. 4 is a detail, vertical, cross section taken on the line 4-4'of Fig. 3 Fig. 5 isa detail, side elevation of a key employed for looking the t pe in place; Fig. 6 is a frag mental, side elevation, partly broken out,

'of the type carrier and type; Fig. 7 is a side elevation, partly broken out, showing an additional improvement; Fig. Sis ,a per of the type carrierand holder; Fig. 11 is a view, partly broken away and partly in end elevation and partly in section, of the type carrier and holder seen in Fig. 1 and Fig. 12 is a side elevation of the modified form of type locking pin or key seen in Figs. 10 and 11.

Referring to said drawings and first to Figs. 1 to 6 inclusive, the reference character A, designates a box like case in which is rotatively mounted a cylindrical type carrier B, on which are removably supported the type holders 14. that contain the type 23. The type carrier may be of any suitable construction and I have here. shown it as comprising two disc like end frame members 6,7, and intermediate disc like plates 9 of smaller diameter than the end frame 'members 6, 7. The end frame members and intermediate plates are spaced apart by sleeves 8 through which extend rods 8" that have nuts 8 threaded on their ends, which clamp the parts together. The type carrier is fixedly mounted upon a shaft or-arbor 8, which is journaled in the end walls of the case A, and has an indicating wheel 25 upon its outer end, bymeans of which the shaft I and type carrier may'be turned to bring any line of type into printing position. As shown, said wheel 25 contains a peripheral groove 26 in which may be placed a card or paper strip a containlng duplicates of or other identifyingdata corresponding to the information appearing on the type on the carrier, and placed in corresponding relation thereto.- Said indicating wheel acts to guide an attendant in setting the type carrier in position to print any information contained on the type thereon. An arrow or pointer 27 on the case cooperates with the data on the strip a, to facilitate the work of setting the type carrier.

The type holders 14 (see Fig. 8) are shown in the form of elongated box like structures of a length to extend between the end frame members 6, 7 and having side walls 15 and 6 end walls 16, between which the type 23 are held. The type and end 'walls are formed with aligned holes 24, 17 (see Fig. 8) adapted to receive a key or locking pin 18 (see Fig. which when in place, looks the type 1 in the holder. The end frame memberst,

7 are formed with circumferentially arranged apertures 12, 13 for the reception of the end portions 19,22, of the keys or pins 18, which protrude beyond the type holders 14, the holes 12 being round, and the holes 13 being round and opening out through the edge of the end frame members 13 through narrow slits 13, (see Fig. 6). The type holders. with the type locked therein by the 20 keys or pins, 18, are secured in placeon the type carrier by inserting the ends 19 of the keys or pins into the holes 12, and bringing the narrow neck portions 22 thereof through g the slits and into the holes 13 and turning fiilthe flat heads 20 thereof, crosswise of the holes. Conveniently, a pair of pinchers is employed for turning the keys or pins. When in place, the type holders rest against the edges of the intermediate plates 9, which act as backings for the type and hold them in a flat condition for printing.

For certain purposes, a duplicate type carrier B maybe mounted on the shaft 8, at the side of the type carrier B and spaced thlerefrom. The construction of the type carrier B is substantially the same as that of the type carrier B and requires no detailed description. 1

At one side of one or both type carriers B, B is a support 30 for a daterthat is, a device for printing dates. shown in the form of a horizontal trough like guideway extending from front to back of the case and secured thereto at places ad{ said guideway 30 is a slide 31 which extendsoutthrough the front of the case and has handle portion 32 by which it may be manipulated. Said slide is divided by cross- 0 wise extending partitions 33 into spaces 34 for receiving type 35 that have type char acters that print the day, month and year, or abbreviations thereof, and as many spaces 34 may be provided as is desired so as to contain type for printing any number of consecutive dates. The slide 31 may be moved back and forth inthe guideway to bring any set of type thereof into printing position, and one or the other of the slide or guideway may have a row of depressions 36 and the other member may have a protuberance 37 adapted to enter said depressions and hold the slide in any adjusted position. The depressions 36 and type 35 are spaced the same distance apart, whereby Said support isjacent its. upper side. 'Slidably mounted inin moving the slide the protuberance may enter the next adjacent depression and locate the type in printing position.

On the top of the case is removably secured a cover 38 having a lengthwise extending slot 39 located directly over the shaft 8, and this position is the printing position of all of the type. mounted upon the case is an impression making device 40 which is spring pressed in an upward direction by springs 41 and said impression making device has an impression bar 42 on its lower sidewhich may be brought down upon a card or strip or sheet interposed between the type and impression bar by striking the handle 43 of the impression making device. On the underside of the cover is an ink ribbon 47 Wound upon suitable rollers, and held in position between the top of the type and under side of the cover. f

In order to automatically bring the lines of type into printing position in succession,

Pivotally.

I have provided a ratchet wheel 44 on the 1 shaft 8 which contains the same number of on the type carrier. A spring pressed pawl 45 engages with the teeth of said ratchet wheel 44, and is connected to and operated by theimpression making device. A spring detent 46 secured to the case, engages the teeth of the ratchet wheel and prevents retrograde movement thereof. In printing cards, the cards are placed on the cover and the impression making device is struck down, bringing the impression bar upon the cardand impinging it upon the ribbon which is interposed between the card and type'that are in printing position. Each time an impression is made, a succeeding line of type is brought into printing position and in this manner a large number of cards may be printed, each with the name of a workman, and the date on which it is printed. In case it is desired to print both sides 0 the card, the carrier B may be set up with type containing duplicates of the names set up in the carrier B but arranged one space behind them, as shown in Fig. 3. A card is then placed over carrier B and the date types, the impression made thereon, and then it is reversed and placed over carrier B which has now been advanced one step, bringing into printing position a duplicate of the line of type contained on carrier B immediately in advance of it. A second card is then placed over carrier B and the date types, and both cards are then printed by pressing down on the impression making device. This procedure may then be carried on indefinitely with other cards.

In the form] of the vention illustrated in Fig. 7, the type carrier is duplicated'and mounted in a case A whihus pivotally lie 7 mounted on and above the case A, and spring name or other data on both sides of a card at one and the same time. In this form, the impression bar 49 for the lower carrier is mounted in the case A and the impression bar 42 for the upper carrier is mounted in the lower case, both being placed in vertical alignment with the shafts of the associated carriers. The cover 38 in this case is fastened to the lower case and contains two slots. Ribbons are provided, one for each carrier as shown. A ratchet wheel 44*, 44 is mounted on each shaft, and a pawl'et5, 459 is connected to each case and coacts with the ratchet wheel in the other case to advance it and therewith the carrier one step each time the device is operated. 1

The card is placed on the cover 38 an the upper caseis pressed down, bringing the impression bar 42thereof down in the card over the set type of the lower carrier, and bringing the set type of the upper carrier down on the card over the lower impression bar 42, thereby making impressions on both sides of the card at one and the same time. As the upper case moves upward under the influence of its springs, the pawls engage the I teeth of their associated ratchet wheels and advance them, and therewith both carriers one step.

In the form illustrated in Figs. 10, 11 and 12, the type holders may, if desired, be formed of sheet metal stripsfolded up to provide the trough like portion 15 and the end lugs or walls 16, as in the preferred form. Apertures are formed in the end lugs 16 of each type carrier and through said apertures extends a locking pin 18 One end 19 thereof may extend through an of the apertures 12 of the end plate 6, an its other end 20 may extend through any of the notches or bayonet slots 13min the end plate 7. Means are provided for releasably securing the type holdeis upon the type carrier and, as shown, said means may comprise a nut 21" threaded upon the threaded end portion 20 of the locking pin 18*. Preferably, a shoulder 22 is formed on, or provided upon the locking pin 18*, which shoulder is arranged to bear against the outer face of one of the adjacent end lugs 16,and against the inner face of the end plate 7. Conveniently, the end 19 of the locking pin may have one or more flat sides engaging with a correspondingly flat side in any of the apertures 12 to thereby prevent the locking pin from turningv when the nut is screwed up to lock the type carrier in place on the frame.

It is understood that any number of type holders may be furnished with the device andthat type may be set up in the type holder, and secured on the type carrier or stored away for future use. It is also to be observed that in case it becomes necessary to print information other than that contained by the type in use on the carrier, such information may be set up in other type holders and substituted for those not required on the carrier.

The type may be formed of type metal or of rubber as is well understood by those skilled in this art.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and described, but intend, in the following claims, to point out all of the invention disclosed herein.
